中文摘要 研究了两种最重要的丛生竹种云南黄竹和龙竹的物理和化学性能。实验结果表明,黄竹的物理性能,如纵横干缩性等优于龙竹,而且黄竹的力学性能如静曲强度、静曲弹性模量及顺纹压缩与剪切强度也比龙竹高。与建筑用木材相比,两种丛生竹的物理力学性能均达到了建筑材料的性能要求。

英文摘要 Two kinds of big sympodial bamboo, Dendrocalamus yunnanicus Hsueh and Den. membraanaceus and their physical and mechanical properties have been studied in the paper. The results showed that Den. membranaceus has better physical properties than that of Den. yunnanicus, such as higher density, lower tangential and longitudinal dry shrinkage. That also showed that Den. membranaceus has stronger mechanical properties in the MOR and MOE, compressive strength and shear strength parallel to the grain. Comparing with some wood species used in architecture, physical and mechanical properties of the two kinds of sympodial bamboo reach the requirement of some wood architecture structure materials.
